OBJETIVE: To evaluate the effectiveness of adenotonsillectomy for the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS) in children by respiratory polygraphy (RP). MATERIAL AND METHODS: Prospective study was conducted on children referred with clinical suspicion of OSAHS. A clinical history was taken and a general physical and ENT examination was performed on all patients. RP was performed before adenotonsillectomy and six months afterwards. Patients with craniofacial syndromes, neuromuscular disorders, and severe concomitant disease were excluded. RESULTS: We studied 150 children (67. 8% male), with a mean age of 3.74±1.80 years and a BMI of 41.70±31.75. A diagnosis of OSAHS was made if the total number of respiratory events, apneas and hypopneas, divided by the total study time (RDI) was > 4.6, using RP before undergoing adenotonsillectomy. The mean respiratory disturbance index (RDI) was 15.18±11.11, with 58.7% (88) of with severe OSAHS (RDI>10). There was a significant improvement in all clinical and polygraphic variables six months after adenotonsillectomy. The residual OSAHS was 14%. The preoperative RDI was significantly associated with persistent disease (P=.042). CONCLUSIONS: Respiratory polygraphy is useful for monitoring the efficacy of surgical treatment by adenotonsillectomy in children with OSAHS.
